NITED STATES ATENT OFFIC METALLIC ROOFING.

SPECIFICATION forming part of Letters Patent No. 319,921, dated J'une 9, 1885.

Application filed January 2|, 1885.

To all whom it may concern;

Be it known that I, LEVI H. MoNTRoss, of Simcoe, Province of Ontario, Canada, have invented certain new and useful Improvements in Metallic Roofing, of which the following is a full, clear, and exact description.

This invention relates to certain new and useful improvements in that class of metallic roofing known as metallic shingles.

The object of my invention is to provide a shingle which is simple in construction, can expand and contract Without making loose joints, and which thoroughly interlocks, thereby being held more securely on the roof and forming very close and tight joints.

The invention consists in the construction, arrangement, and combination of parts, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of aseries of shingles or plates on a roof. Fig. 2 is a cross-sectional view on the linear as, Fig. 1. Fig. 3is a crosssectional view on the line y y, Fig. 1. Fig. 4 is a perspective view of a saddle for holding the lower end of the shingle. Fig. 5 is aplan View of parts of shingles, showing a different fastening device.

The body of the sheet-metal shingle A may be made square,0r have any other rectangular shape,and is provided with the ribs B B B which are triangular in cross-section and project from the face of the shingle and extend from top to bottom. The left-hand-edge rib, B, need be but half a rib, as shown in Fig. 2, and the right-hand-edge rib, B must be arranged a short distance from the edge to form the joint-flange O. A short distance inward from the left-hand-side rib, B,'the metal is doubled to form a pocket, D, parallel with the rib B, the open side of the pocket facing the said rib. To form the pocket, a rib is first formed to project from the top of the plate, and is then doubled over toward the rib B. The pocket is not closed completely, so as to permit inserting the flange 0. Each ribB B is provided at short distance from the lower end with a longitudinal slot, E. A triangular or inverted-V-shaped sheet-metal saddle, F, having latcrally-projecting side flanges, G, is

(No model placed on the upper end of each rib, and is held down by nails passed through nail-holes H in the flanges G, and corresponding in position with the nail-holes in the plates or shingles at the sides of the ribs. Parts'of the sides of the saddle are punched out to form upwardly-projecting tongues J. The plates or shingles A are provided at the ends and middle with transverse ridges K, and with diagonal ridges L between the middle and end transverse ridges, which ridges stiffen the plates and prevent buckling. If desired, the transverse ridges in the center of the shingle may be dispensed with and the intermediate ribs, B, terminated short distances from the ends of the plate and intersected with the diagonal ribs, whereby diamond-shaped fields are formed, which may be left plain or provided wit-h raised figures. In place of the saddles F, clips M may be soldered, riveted, or otherwise secured on the plates or shingles near the upper ends and bent over the bottom edges of the nextplates above, as shown in Fig. 5. The shingles are stamped or pressed in suitable dies.

In place of securing the saddle F on the upper end of the lower shingle and placing the lower end of the upper shingle upon the said saddle,the saddle may be placed on the sheathing and the upper end of the rib of the lower shingle placed upon the saddle, and the lower end of the rib of the upper shingle placed upon the upper end of the rib of the lower shingle, and the tongues of the saddle passed through the corresponding slots in both shingles and then bent over.

The shingles are fastened on a roof in the following manner: In laying on a roof a narrow strip of iron is first nailed to the sheathing along the eaves. The first course of shingles have their' lower edges folded under to receive and embrace thestrip of iron first nailed on, and this gives a double thickness along the caves to resist bruising the edge by ladders placed against it. The bottom row of shingles is first laid, and saddles F are placed and secured on the upper ends of the ribs B B ,but not on the edge rib, B. The next row of shingles is then placed on the roof in such a manner that the lower ends rest upon the saddles F. The tonguesJare placed through the slots E, and then the tongues J are bent down on the sides of the ribs,as shown in Figs; 1 and 3. The upper transverse ribs or ridges, K,of 7 the lower shingles pass into the transverse ribs be formed on the shingles used at the edges of the roof, as at the left-hand side of Fig. 1.

Having thus described my in veutioml claim as new and desire to secure by Letters Patent- 1. Thecombination, with the metal shingles 20 or plates A, having ribs extending from top The slots E are longer to bottom, and having slots E in the lower ends, of the saddles F, shaped to fit the ribs, and 7 having tongues adapted to be passed through the slots in the ribs and lapping opposite inclined sides of the ribs, substantially as herein shown and described.

2. The saddle F, with side flanges, G, and tonguesJ J ,struck from the top or ridge from opposite sides thereof, substantially as herein shown and described.

3. A metallic shingle having ribs B B B extending from top to bottom, the transverse ribs or ridges K, and the diagonal ribs or ridges L, substantially as herein shown and described.
